Okay ... I have uninstalled SENDMAIL and reinstall SMAIL. I can send e-mail, however I cannot recieve e-mail. When I send it, the Return-Path line on the e-mail reads <root>. In my SMAIL config file, I have changed the visible name to my full e-mail address: dmdp@miracle.net, and change the hostdomain to miracle.net. I have also added a line postmaster=dmdp@miracle.net. I don't know what else to do. Thanks, Denis
